There is a groups.io group for this project (SoftwareControlledHamRadio). However, newer projects by the author have taken over the content. I wrote my own firmware for the VFO and made it available

If by any chance you live in South Texas check the attic many builders are using a foil backing on the roofing boards they put down to help with heat. I used an end fed in an attic for over a year and

I'll echo Don's comment about the end-fed antennas. I have the PAR 40M/30M end-fed and very happy with it. It has a single trap about 45 feet out from the feedpoint, and an overall length of 54 feet.

I am going to need HOA antennas for at least about 3 to 4 mo. I have 20 and 40 dipoles on hand that I can put in my attic under my standard composition shingles roof...or I could put up a backpacker

I have the 40 meter Modular QRP CW transceiver from the August 2016 QST. Does anyone know where I can find a copy of the firmware? It was working fine until I recently took it out of mothballs, only
